Where to Get Help
326 Walker Hall
I am always happy to help you in office hours. An open door
means that I am on the floor somewhere, so come look for me.
Check this for access to
the other class web pages. On web pages, an underlined phrase
means a link.
Check this after each class meeting for daily class overviews,
and short term nightly assignments!
Dr. Sarah's MAT 1010 WebCT is accessible by password from myWebCT
after following the lab 1 directions.
The Bulletin Board
is the easiest way to ask a math question outside of class and office hours.
You are responsible for reading all posts - you should check the bulletin
at least twice a week.
I prefer that you use office hours since it is easier to discuss
material in person, but if you can not make them, then the newsgroup
is a great alternative.
I usually check the newsgroup numerous times every day including the
I usually check e-mail once a day during the week.
is the easiest way to
contact me outside of class, office hours and the WebCT bulletin board.

- Elementary Linear Algebra
by Larson and Edwards. Houghton Mifflin 2000
- Linear Algebra Modules for Interactive Learning Using
Maple by Herman
- handouts - given out in class or lab or on the web
- access to a web-browser and to Maple V or VI
An introduction to linear algebra,
via selections of Chapters 1-7 of the textbook and Maple modules
Be exposed to theory and proofs
Learn about applications of linear algebra
has been designated as a
computer designated course. We will be using Maple to satisfy
Topics and Objectives
Systems of Linear Equations
Matrix operations and inverses
Vector geometry in 2 and 3 dimensions
Vector spaces, dimension, rank of a matrix
Eigenvalues, eigenvectors and diagonalization
Material is covered very quickly.
Do plenty of exercises, more than those that are assigned.
Plan to spend at least 5-7 hours
per week, out of class, on average, on this course.
Attendance and participation are expected and required.
Please try to be punctual in attending, as I try to start each class on time.
If you must be late to a class, or must leave early,
then do still attend, although
you can expect that the portion of the class that you miss will be deducted
from your attendance allowance.
This class does not follow the standard lecture format.
There will be days when the activities are designed to be completed
during class and handed in at the end of the period.
Thus, attendance is required at ALL lecture and lab periods.
You are responsible for all material covered and all announcements
and assignments made at each class, whether
you are present or not. You are also responsible for announcements
made on the web pages, so check them often.
Certain homework or assignments will require use of a computer with
web access and Maple, as
this is a computer intensive designated course. Either you will be given
some time in lab to do the assignment, or you will have at least
36 hours to complete such an assignment - enough time
to access a computer from school if you do not have one at home.
If, due to work or other responsibilities, you cannot
access such a computer
at least once every 36 hours, then you should drop out of this section.
When writing up work, be sure to give acknowledgment where it is due.
Submitting someone else's work as your own (PLAGIARISM) is a serious
violation of the University's Academic Integrity Code.
Asking questions, and explaining things to others, in or out of class,
is one of the best ways to improve your understanding of the material.
This course is to be an environment in which everyone
feels comfortable asking questions,
making mistakes, offering good guesses and ideas, and is respectful to
You should explore each problem
and write out your
thinking in a way that can be shared with others.
Focus on your own ideas.
Turn in projects or prepare to present problems
even if it they are not complete, even if only to say, "I do not
understand such and such" or "I am stuck here."
Be as specific as possible. Conjecture.
In this course, you will be challenged with problems that you have never
seen before. I do not expect you to be able to solve all the issues
immediately. Instead, I want to see what you can do on your own.
Out in the real world, this is important, since no matter what job
you have, you will be expected to seek out information and answers
to new topics you have not seen before.
This may feel uncomfortable and frustrating. I understand this
and want to help you through the process.
It helps to remember that
there are no mathematical dead-ends!
Each time we get stuck, it teaches us
something about the problem we are working on, and leads us to a
deeper understanding of the mathematics.
In the real world though, you are not expected to face your work alone.
You will be allowed to talk to other people
may even be expected to work with other people.
In this class, you are also not expected to face your work alone.
I encourage you to talk to me often in class, office hours,
and the bulletin board,
and group work will also be encouraged.
I am always happy to help you in class, during office hours (or by
appointment), or on the WebCT bulletin board, and will
try to give you hints and direction.
At times though, to encourage the exploration process,
I may direct you to rethink a problem
and to come back to discuss it with me again afterwards. This occurs
when I believe that the struggle to understand is imperative for your
deep understanding of the material.
